The chemistry of alkylstrontium halide analogues was examined. In the presence of metallic strontium, the Barbier-type alkylation of imines with alkyl iodides proceeded smoothly at room temperature under an argon atmosphere to afford the corresponding alkylated amines in good yields.

There are disclosed a lactam derivative of the formula:
wherein R1 is a substituted or unsubstituted phenyl group; R2 is a substituted or unsubstituted phenyl group, a cycloalkyl group or a nitrogen-containing 6-membered heterocyclic group; Z is oxygen atom or sulfur atom; and n is an integer of 2 or 3, and a salt thereof, and a preparation thereof.
The above lactam derivative is novel and useful as a pharmaceutical compound. Accordingly, pharmaceutical preparations are also provided, together with the use of such derivatives for the manufacture of a medicament having valuable therapeutic properties.

inert atmospheres with dry volatile organic solvents and often low temperatures, the addition of highly polar organometallic compounds to non‐activated imines and nitriles proceeds quickly, efficiently, and chemoselectively with a broad range of substrates at room temperature and under air with water as the only reaction medium. Secondary amines and tertiary carbinamines are furnished in yields of up to
